TERMINAL CECTION FR- SPARJQPLUGS.

pntic-ation filed (let f ZZ om it concern ABe -it lrnown that I, JAMES P. BLAUVELT, a citizen of the United States, and a resident of Nyack, in the county of Rockland and State ot' New York, have invented a new and improved Terminal Connection for Spark-Plugs, of which the following is a full, clear, and exact description.

The object of the invention is to provide end'improved terminal connection for similar devices arranged i 1 iient attachment of a clip electrode member of the spark plug aar to Went losing o f the nut em ployed for-'tastening the clip 1n position on the spari:

ln order to accomplish the desired result, use is made of a clip connected withan electrical conductor and provided with a bearing for the nut oft' the spark plug to turn in, the nut serving to clamp the clip in place on a nen spari; plu

the sparlrplag.

A practical embodiment of the invention is represented the accompanying drawings 'forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the terminal .connection as applied to a spari: plug; Fig. 2 isa plan View of the clip; and Fig. is a side elevation of the nut for fastening the clip in position on the spark plug.

The terminal connection is shown applied a spark plu-.0' A of usual construction and haring a central electrode member B on which screws a nut C for clamping the termina clip in position on the spark plug A, as plainlyindicated in Fig. l. To the clip D is soldered or otherwise secured one end oit' the electrical conductor E covered iulation E', the end of which mgaged y the split shank D of the clip 1ste-n thelatter to the electrical confning l)L for the passage of the member' n. and the said elip D is 'further provided with a return bend D" provided with a bearin which is mounted to rotate a j0ur- C formed on the upper end of the. nut (l nai so that the latter is held permanently between the clip D and the return bend D3, and the nut can be readiiy rotated so as to screw it on the member l or unser-ew it 'thi-:retrete lt will be noticed that when the aperture D2 of the clip D is engaged Specification of Letters Fatent.

The Clip l) is provided with an .iiatented iilay el, finiti.

with the upper end of the electrode member B then the-screw is held inproper position for screwing on the member B, and in screwing the nut C down on the member B the clip D is finally clamped in position between theznut C and the collar F held on the spark plug A. The journal C is preferably formed by providing the nut C with a` reduced extension C2 formed with an annular groove, and the bearing D4 is preferably formed in the return bend D3 by providing the latter with a lengthwise extending split to providesplit members having registeringl and rotatably ,carried on the clip D, Ait is evident that the said nut cannot be readily lost and the clip can be quickly connected with the spark plug or removed therefrom whenever it is desired to do so.

Although I have shown and described the terminal cpnnection as particularly ap- 'plicable to spark plugs, it is evident that the said terminal connection4 may be used for other devices of a similar nature.

Having thus described my invention, I claim as new and desire to secure by Letters Patent z l. A termin-al connection, comprising a clip adapted to be connected with an electrical conductor, 'said clip having oppositely arranged and spaced non-resilient members provided with registering, openings one of the members havin(r a slit lead' plugs having a. central electrode member',

" a nut screwing thereon, and a clip connected i plugs having a central with an electrical conductor and having a return bend provided with a bearing, 1the said nut extending between the clip and the return bend and having a journal engaging the said bearing.

3. In a terminal connection for spark plugs having a central electrode member, a

nut screwing thereon, and a clip connected with an electrical conductor and having a return bend provided with a lengthwise eX- tending split forming split members having registering recesses at their opposite edges to form a bearing for the said niit to turn in.

4. In a terminal connection for spark electrode member, a

nut screwing thereon, and a clip connected With an electrical conductor and having a c Areturn bend provided with a lengthwise eX- teiiding split forming split members having registering recesses at their inner opposite ameter, and a nut having a reduced pox'- tion engaging the larger opening vet thel member, the portion of the nut except that engaging the opening being wholly between the said members.

In testimony whereof I have 'signed my name to this specification in the presence of two subscribing witnesses.`
